There's been a lot of work put into distilling "free market" into its most radical interpretation, and lots of people just aren't open to bringing much nuance or pragmatism to bear upon it any more. Many lessons learned painfully in late 19th and early 20th century have been forgotten and the counterweight and containment policies that they earned now tend to get ignored or dismantled.
Hobbes arguments can rationalize any Nash Equilibrium.
Of course this could be offered. But, no one wants to do it because it's a thankless job. And if you're going to do a thankless job, you'd probably rather get paid a lot of money to do it than very little
Point is, it's easy to screech "predation" or whatever but the problem is that every one of these things has some justification that can be used in the abstract.
It does legitimately cost more to run a store like Dollar General than Walmart so the same can of beans has to cost more on their shelf for the same margin.
How much more, how much is justified? I don't know.
They can do this because they are operating in other areas with predatory prices, giving them the ability to operate at a loss, and relying on the fact that at least some of those areas are not being challenged by non-predators.
Everybody seems to be playing the game right in this scenario. Interesting to try to come up with a good counter.
Yes, I guess well capitalize companies could offer unrealistically low prices, but on the other hand, any kind of co-op or community driven organization has the benefit of not needing the margins. Dollar store investors are there to make a buck, if their capital isn't getting reasonable returns will ultimately exit the business and move somewhere else.
Just look at food recipes American corporations feed to Americans, and their different recipes for Europe that look more like the American recipes circa the 1990s. Everything in America is optimised to the max permissible bad action.
In the EU and UK, shame still motivates better behaviour.
Every single problem the USA has comes down to the fact that shame, in the USA, stopped functioning in the late 1970s.
Yes, lots of businesses have thin margins. But the law (such as contract law and the laws against consumer fraud, which are implicated here) sets the things that a business can’t economize on in order to meet those margins. It’s the same as food safety: restaurants also run really thin margins, but they’re not allowed to store the meat on the counter because refrigeration is too expensive. If they do that, they get shut down by the health inspector.
Businesses “should” comply with consumer fraud laws for the same reason they “should” comply with health codes.
